Crispi Attiva Mid GTX boots are ideal for the light and fast hunter who wants to stay nimble, mobile, and agile while keeping their feet dry and protected during early-season hunts. The ultra-soft comfort of a leather/synthetic upper, Elastoflex midsole, and Vibram sole are a combination that makes for a unique mix of fast and light with durability not often found in hunting-specific boots within this category. The Elastoflex midsole delivers a perfect weight-to-impact absorption ratio specific to hunting situations and additional uses. The boot provides additional flex stability to give this boot a Flex2 rating. For ankle stability, Crispi uses their proprietary Thermo Wire Technology (TWT) which is an innovative system to provide the upper with greater stability, ankle support, and protection without added weight. The Attiva Mid is complete with a speed lacing system and a tidy lace garage on the top of the tongue.
